release-core-test

release-core-test is a skill for Claude Code, Codex from cyrusagents/cyrus. It costs 114 tokens per session (1,509 once invoked), scanned A, original, Apache-2.0.

A test-release workflow for publishing the cyrus-core package, and sometimes claude-runner, as an npm prerelease. It is for changes spanning CYPACK, an edge worker and command-line tool, and CYHOST, a Vercel-hosted web interface.

In plain words
What is it for?
Use it while testing cyrus-core changes across the edge worker, CLI, and hosted GUI. It installs dependencies, builds the workspace, and publishes the test prerelease under npm’s test label.
Why use it?
It lets a hosted test interface use an unreleased version from the current repository without performing the full release process. It does not create tags, GitHub releases, commits, pull requests, or publish unrelated packages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

release-core-test scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Release Core (Test)

Publish ONLY the cyrus-core package (and claude-runner if needed) as a dev/test prerelease to npm under the test dist-tag. This is a developer convenience for iterating on cyrus-core without going through the full release flow.

What this skill does NOT do

This skill is intentionally minimal. It does NOT:

  • Update CHANGELOG.md or CHANGELOG.internal.md
  • Create a git tag
  • Create a GitHub release
  • Move any Linear issues
  • Open a pull request
  • Commit the version bump (the bumped package.json is left as a local working-tree change)

It also does NOT publish any other workspace package (no edge-worker, no cyrus CLI, no linear-event-transport, etc.). The only exception is claude-runner, which is republished if and only if its workspace:* reference would otherwise resolve to an unpublished version (see step 3 below).

Workflow

1. Install dependencies from repo root

pnpm install

2. Build all packages from repo root

pnpm build

Building all packages ensures workspace:* dependencies are resolved before publishing.

3. Determine whether claude-runner needs republishing

cyrus-core depends on claude-runner via workspace:*. When cyrus-core is published, that workspace:* is rewritten to the version currently in packages/claude-runner/package.json. If that version isn't actually on npm yet (because claude-runner has local changes since its last publish), consumers installing cyrus-core@test will fail to resolve the dependency.

Run both of these deterministic checks:

# (a) Is the local claude-runner version already on npm?
LOCAL_CR=$(node -p "require('./packages/claude-runner/package.json').version")
npm view "cyrus-claude-runner@${LOCAL_CR}" version 2>/dev/null

# (b) Does claude-runner have uncommitted/unpushed source changes since its last publish?
git diff --quiet HEAD -- packages/claude-runner/src packages/claude-runner/package.json && echo "clean" || echo "dirty"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
